In the formula, is the weight of the item index, which can be determined and satisfied by methods such as principal component analysis and analytic hierarchy process. The greater the gray correlation degree, the better the index of the group, so the parameter combination with the largest correlation degree is the best scheduling plan.

Where, is the weight of the index, which can be determined by principal component analysis, analytic hierarchy process and other methods. The greater the grey correlation degree, the better the indicators of this group. Therefore, the parameter combination with the maximum correlation degree is the best scheduling scheme.<br>

Type, which is the weight of the first index, can be determined by principal component analysis, analytic hierarchy process and other methods, and meets the requirements. The larger the grey correlation degree, the better the index of this group, so the parameter combination with the largest correlation degree is the best scheduling scheme.
